The ViewCube is a navigation tool that is displayed when you
are working in 2D model space or 3D visual style. With ViewCube tool, you can
switch between standard and isometric views.

The ViewCube tools is a persistent, clickable and drag gable
interface that you use to switch between standard and isometric views of your
model. When you display the ViewCube tool, it is shown in one of the corners of
the window over the model in an active state. The ViewCube tool provides visual
feedback about the current viewport of the model as view changes occur. When the
cursor is positioned over the ViewCube tool, it becomes active. You can drag or
click the ViewCube, switch to one of the Available preset views, roll the
current view, or change to the Home view of the model.

The ViewCube tool is displayed in one of two states:
inactive and active

Inactive= appears partially
transparent

Active= it is opaque and may obscure the view.

In addition to controlling the inactive opacity level of the
ViewCube tool, you can also control the following properties for the ViewCube
tool

Size, Position, Display of the UCS menu, Default orientation
and the Compass display

Vents and drains on high and low points of lines
respectively, to be used for hydrostatic testing, are not shown, as they are
established on the piping arrangements drawings. Process vents and drains are
shown.

Valves on the P&ID
1. Show and tag process and service valves with
size and identifying number if applicable. Give pressure rating if different from
line specification.

Iron and Pipe Sizes
Initially established for wrought-iron pipe with wall thicknesses designated by the term ‘Standard
(Weight)’, ‘extra strong’, and ‘double extra strong’. Before the schedule
number scheme for steel pipe was first published by the American Standards
Association in 1935, the iron pipe size were modified for steel pipe by
slightly decreasing the wall thicknesses (leaving the outside diameter
constant) so that the weight per foot (lb/ft) equaled the iron pipe weights.

Wrought-Iron pipe (not longer made) has been completely
supplanted by steel pipe, but schedule numbers, intended to supplant iron pipe designations
did not. Users continued to specify pipe in iron size terms, and as the mills
responded, these terms are included in ANSI standard B36.10M for steel pipe. Schedule
numbers were introduce to establish pipe wall thicknesses by formula, but as
wall thicknesses in common use continued to depart from those proposed by the scheme,
schedule numbers now identify wall thicknesses of pipe in the different nominal
sizes as ANSI B36.10M states “as a convenient designation system for use in
ordering”.

Stainless-Steel Sizes

American National Standard B38.19 established a range of
thin-walled sizes for stainless-steel pipe, identified by schedules 5S and 10S.

As many of you all know, there has been many times that your installation of Civil 3D has become corrupted or you have changed things that has messed up your program. Customers would call us and a Clean Install or Secondary Install would have to be initiated. This is a pain to many customer because of having to located folders and delete them, and to delete registry keys.

Well thanks to Almas Suljevik from Autodesk, we have a one-click solution, Reset User Settings.
